Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
English Walnut Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the milk or water and baking powder.
Gradually add the flour, mixing until just combined.
Make the filling
For the filling, shell and pound the walnuts.
In a saucepan, combine the walnuts, brown sugar, enough milk to moisten, and a lump of butter the size of an egg.
Cook over medium heat until the mixture thickens and can rope off a spoon.
Assemble
Layer the filling on the cake and sprinkle with additional walnuts, repeating until all is used.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving a light, tender crumb and rich flavour.
- Eggs
- Add structure and richness, binding the batter as they set in the oven.
- Flour
- Forms the cake's structure once mixed in and baked.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- English walnuts
- Provide the nutty flavour and crunchy texture of the filling.
- Brown sugar
- Sweetens the filling and helps it thicken into a moist, caramel-like mixture.
The step that matters
Cooking the walnut filling until it thickens. Cook over medium heat until the mixture thickens and can rope off a spoon. Undercooked filling stays runny and soaks into the cake, while overcooking can make it stiff and sticky once cooled. Sugar and milk thicken as water evaporates and the mixture reaches the right concentration.
